Was Jo killed off? I never got to see it. Also if anyone knows when it will be on again, please tell me!

No Jo was thankfully not killed off. That would of been a sad reunion if she was.
I don't really know if they're gonna air it again. There's always a chance, if ABC doesn't have any more of those "Wonderful World of Disney" movies. We should ask if they would do a re-run. I doubt it, but there's always a chance.
